Mark,
Those could be valuable some day as already mentioned. It would help greatly to have each signed by the winner (Earl and Johnny in this case) and some other documentation as well. A news paper article, an article from AZ or any other pool magazine, dated and describbing the event and mentioning the winner would help prove the authentisity of the article. A picture of (Earl and/or Johnny)accepting the award and check would be great. The finals bracket sheet used at the tournament would be worth a lot too. Those checks are large enough you could probably mount those credentials right on the back.
I leared all of that watching The Antiques Road Show for the last four years. The actual artical is always worth something but the value increases with each piece of documentation that you can provide. So get it now, while you can. Might be hard to get (or cost alot) in 20 years.
